Counter Example For A Japan Trip

There is an Western fellow in the pub. He moved seats (without asking), moved furniture (blocking the narrow walkway), and has his shoe-clad feet propped up on another seat – all so he can monopolize the one power outlet in the place.
Oh, and he left trash where he was sitting before.
I thought he was an American. I felt some misplaced responsibility for correcting him. How to do so? I was formulating a narrative where neither the pub nor the dude would get embarrassed.
And then the dude opened his mouth. He’s European. And thus, I am not his keeper.

Be nice with what you write.
